hey guys i'm torn between the castrol edge 5w-30 and the motul turbolight 4100 10w-40 for my next service. would like to know pros and cons for both and past experiences. i've read the oil thread and i know the motul gets heaps of good praise but i want to know about castrol edge more from the people that use it especially with the hotter months closing in.

another question i wanted to know is if castrol vmx 80 will be fine for my gearbox and if not what other alternative around that price range would be better? also what can i put into my diff?

i have a daily r33 gtst series II with 105,000kms. thanks

5w-30 will protect better when cold, but depending on the condition on the motor the hot rating might be too thin, you'll only know you have blowby issues is by going ahead and trying it.

hi there guys, i'm facing the same problem choosing the correct oil for my v35 ,engine model vq25dd, hope one of you may be able to advise me of a suitable oil. I live in botswana and it's a similar climate, very hot, i have a choice of shell 25w-60w,15w-40w, castrol magnatic, havoline semi synthetic? which do you think i should use

No other choices than the above 3 (I'd probably chooce Shell or Havoline, hate lowspec Castrol oil)?

If 25w-60 and 15w40 are the only options, then 15w-40 I would choose, 25w is just too thick when cold.

thanks for your input guys. ended up getting the motul.

been recommended vmx m and not the vmx 80. does anyone know the difference? also would like to know if the nulon 75w-90 semi synth smooth shift gear oil would be suitable. nulon suggests their 75w-85 100% synthetic but would liek to know if the semi synth will do fine?

Castrol Transmax M is used for automatics

its been proven before and if your gbox is in good nick stick to vmx80 and you will be fine

In a good condition RB25 I HIGHLY recommend Fuchs 10w30, Bursons stock it, Have been running it in the Stagea for 40k km, motor is cleaner, smoother, more economical than when i first got it, i have run motul once, wasnt a fan.

Their 10w40 is another option. Motul 300v I understand, but the lower end stuff I dont get the hype. Chuckie has had his oil regularly tested up to 20k km and the fuchs doesn't deteriorate.

Same, smells nice too.. :(

Had a workshop replace the transfer case for me, they put in decent gearbox oil but it doesn't like it, 4th and 5th synchros are a bitch. Going to dump it and go back to the vmx80 that I was running before without an issue.

Ive never had a problem with castrol edge, and ive been using it for about 1.5yrs now, I use 10w60tho. I believe some drift teams are sponsored by it and havent lost an engine.

I haven't had any probs with Castrol Edge 5w-30 for the 3.5yrs I've had my car. it's the only decent 5w-30 readily available off the shelf that i've found and it's the recommended weight in my manual.

my car is NA though.

it would be interesting to know how many of the above mentioned oils are actually certified as meeting there advertised spec. And viscosity as in the thickness is not the spec either. Should be running a SL spec oil or higher which is commonly a semi-synthetic at the very least. Check on the back of the packaging. If its not got the API stamp, then you dont actually know what you are getting and 80% of oils retailed off the shelf havent as it costs big dollars to have a product certified.

Repsol oils are what i used in my shop for 5 years for this reason.

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
